Cooling of the air is one of the most common psychrometric processes in the air conditioning systems. The sensible cooling of air is the process in which only the sensible heat of the air is removed so as to reduce its temperature, and there is no change in the moisture content (kg/kg of dry air) of the air.
I think the answer is correct.
I think the answer is correct.

Insensible cooling wbt decreases, dew point temp and dry bulb temp remain constant and relative humidity increases and specific humidity remains const.

In sensible cooling;
WBT decrease.
Relative humidity increase.
DBT constant.
Specific humidity constant.
So the answer will be option A) WBT.
WBT decrease.
Relative humidity increase.
DBT constant.
Specific humidity constant.
So the answer will be option A) WBT.

During sensible cooling- dbt, wbt decrease, dew point temp remain constant, relative humudity increase, specific humudity remain constant.

After sensible cooling of air it will contain moisture in air. And as the moisture decreases then it will be dry air free of moisture.

Hey I think during sensible cooling wet bulb temperature also decreases in addition to dry bulb temp. Have a look.

In this process D.B.T. and W.B.T. decreases, relative h increases and sp humidity remain constant.

Wbt - constant.
RH - increases.
Dbt - decreases.
Sp.humidity - constant.
RH - increases.
Dbt - decreases.
Sp.humidity - constant.
